Be it known that I, WILLIAM J. FRIsIn, a

citizen of the United States, and a resident of Chicago, in the countyVof Cook, State ofl Illinois, have invented certainnew and usefulImprovements in Oil-Cups, of which the following is specification.

inventionv relates Yto oil cups, particularly to that class of cupcomprisinga nipple member permanently connected vwith the surtaces tobelubricated, and an oil reserf provisionis made to avoid it. The mainobject of my invention is to provide efficient means whereby thereservoiror cup member may be readily appliedto or detachedfrom thenipple member together with improved means Jor preventing inadvertent orself-y separation of the cup member from the nipple member,

I On the accompanyingV drawing, I have shown a constructionrin which myimproved mechanism is embodied. On this drawing- Figure 1 is a sideelevational view of the oiling structure, i s.

Fig. 2 is an enlarged bottom view of the cup member, Y

Fig. 3 is a side elevational view of the nipple member.`

Fig. 4 is an enlarged plan view of the nipple member, and

Fig. .5 isanenlarged vertical dlametral sectional view of the entirestructure.

The nipple structure N, is ^preferably formed integral of sheet metaland cornprises the upper cylindrical section 10, whose lower part 11 isconical, the intermediate polygonal sectionv 12, Vand thelower threadedsection 13 for engaging in the threaded entrance of a passageway leadingto surfaces to be lubricated. The upper cylindrical section 10 isexternally threaded as y. clearly shown in Figs. V3 and 5.@The cup i Ying thet the cup,

member is constructed of sheet metal andA comprises the cylindrical bodypart 14 having the dome Shaped top 15. The` cup V1s closed at its lowerend by the closure member designated as ya ywhole 16, and comprlsop 17extending diametrally across `and the downwardly.y extending cylindricalflan ge 18 which is threaded on its kSpecrzificaton of Letters Patent. l

' interior toy fit thethreads onithe upper` section 10 of thenipplemember. lIn the aI-, rangementshown, the wall 17 has at its centcr the opening'19 surrounded bytheupstanding ilange 2Oy in whichopening and flange is seated at its lower end the tube 21v which extendsupwardly well to the Vtop of the cup. The cup closure* member and tubeare thus rigidly connected together. The cup is strengthened andfinished 011" at. its lower end by the flange 22 extending laterallyunder thecup edge from the lower Vend of the side wall 18 of the closuremember as clearly shown in Fig. 5. u

Securely seated within the upper ksection 10 of the nipple member is theinverted cup member 23. The horizontal wallof this member has thecentral opening 24 surrounded by the flange 25 which receives andsupport-s the feed spindle 26,.this spindle receiving the tube 21` ofthecup member when the cup member is screwed on toV they spindlemember.V The spindle supporting" base 23 has the annular depression orpocket 27 for receiving the sealing washer 28the wall 17 ofthe oil cupclosure ymember having a similar pocket 29for receiving thepuppersection of the washer when'the cup and nipple structures are securedtogether. When the 'cup structure is to be used, the

nipplemember is secured to the support leading'tothe vsurfaces to belubricated.

The cup member is then inverted Vand oil filled therein through Vthetube 21 vent open-v ings ObeingV provided in saidtube near the bottomthereof for the escape of air while the cupV is being filled. The cup isthenl righted'andfapplied with its tube receiving the spindle 26, thecup being then turned to bring its threads into engagement with those ofthe nipple structure until the cup and nipple members are tightly drawntogether into clamping engagement with the washer 28, there being thenno chance for direct flow vof oil fromthecup into the nipple 'memberVhen thevehicle is traveling the cup structure is jolted and bodilymoved with the vehicle so that oil therein is splashed up and into thetop of the rspindle 26. The domeshap'ed top 15 assists in deiiectingthrown up oil into the dischargev spindle and the upper end of the tube21 isv v also cut out to leavel passageways 31 for the oil tothedischarge spindle. The/spindle is of such diameter relative tothe'k tube21 that ithe tube will readilyv receive the spindle and allow the cupmember to be readily applied to the nipple member. .y During heavytravel of a vehicle, the

`oil cups'are'violently agitated and-jerked and jolted and even withthethreaded engagement between the cup member andthe nipple member asshown on the drawing, the` cup member is apt to work loose from the4kporting member 23.

nipple member. rlhe important object of my invention is to prevent suchinadvertent separtion or loosening of the cup member.

The mechanism of my invention is clearlyv shown in Fig. 5. Within the`chamber ,formed by the upper section of the nippleV member and thespindle supporting member 23 is arranged a. coil vor spiral spring 32which seats on thefloor of the chamber and whose upper end 33 isdeflected vertically and extends through the opening 3st provided in theupper wall of the spindle suprIhe wall 17 of the closure member 16 forthe oil cup is deflected toY provide a circular row of depres- 'sions 35for receivingthe end 33 of the spring Y when the cup member is threadedintouplace on the nipple member. Then the cup member reaches the bottomof its .travel during application thereof to the nipple member, thepockets 35 will receive the spring end 33 and the end will be forceddownwardly and the spring compressed. The resistance offered by theengagement of the spring pressed end in the pockets is sufficient tolock the oil cup and nipple member together and prevent inadvertentseparationthereof, while at the same time, the cup can readily be turnedto be applied to or removed from the i nipple member. All the parts ofthe cup besupport, an oil cup member having a closed' bottom, aninternally threaded flange on the lower end of said cup member havingythreaded engagement with said nipple member, said cup member having anoil outlet for communicating with the nipple member, depressions in thebottom wall of said cup'inember, and a spring` pressed finger on saidVnipple member I forv frictionally engaging with said depressions whenthe cup member is applied to the nip'l ple member wherebyseparatioiiofthe members is prevented.

i 2f In an oiling device, the combination of a nipple member havingexternal threads at its upper end, a cup member adapted at its lowerendV for threaded engagement with said nipple threads, a bottom wall forsaid cup member, an oil outlet through said wall for communicating with.thev nipple-member, the upper kwall of said nipple member having anopening, a spring housed within said nipple member and having its endprojecting upwardly through said opening, the bottom wall of said oilmember having detent depressions forl cooperation with said spring endto lock the cup member to the nipple member after "threaded engagementof such y members.A

3. In an oiling device, the combination of a nipple member having a topwall and lhaving threads, `a cup member adapted at its lower end forengagement with said threads to be thereby held on the nipple member,said oil cup being closed at its lower end by a wall and said wall andthe upper wall `of said nipple member having oil passageways for theflow of oil from the cup to the nipple, the upper wall of the nipplemember having an opening, a coil spring housed within said nipple memberand having its end projected through said opening, and detentdepressions in the bottom wall of said cup member for c'oepearting withsaid spring end to lock the cup member against inadvertent separationfrom said nipple member.

4. Iny an oiling device, the combination of v a nipple member adaptedfor beingl secured on a support, the upper end of said nipplemember'being cylindrical and having external threads, a cylindrical cupmember having internal threads at its lower end for en- Vgaging with thenipple threads, a wall above the cup threads closing the lower end ofsaid cup, means affording oil flow passageway between the cup and nipplemembers when said members are screwed together, said cup `wall havingdetent Vformation on its under side, and a helical spring held'withinthe nipple member with one end projected in the ypath of said' detentformation to cooperate therewith to lool; the 'cup member against''inadvertent separation Y from the nipple member.

5. In an oiling device,fthe combination of nipplemember adapted to besecured on a support, a cup member having threaded connection with saidnipple member, a bottom wall for said cup member,a removable top wallfor said nipple member, said walls having registering openings for theflow of oil from the cup member to the nipple member; a spring housed'within said nipple member and having its endl projecting upwardly to thenipple top wall, the bottom wall ofsaid cup member having detentformation for cooperation with said spring end to lock the cup member tothe nipple member after threaded engagement of such members.
